13 Claims.

The invention relates to flttings for adapting openings in the wall of a metal container or the like for closure by a threaded plug.

An object of the invention is to provide a de- 5 vice of the character described in which the parts thereof are so designed and arranged for connection with each other and with the container, that without requiring connection of such parts and wall by interlocking seams or joints, no axial or rotative displacement of the parts relative to' the wall may take place even during extremely rough handling of the container.

Another object of the invention is to provide as part of the device, without any extra parts, a means permitting the ready and effective attachment to the device, of a cap or covering which will fully shield the device and its connection with the container wall, against any unauthorized or undetectable access.

A further object of the invention is to provide a fltting of the character-described which may be made flush with the container wall on the inner side without causing an undue protrusion of the device and the shielding cap or enclosure therefor at the exterior of the container.

A stillfurther objectvis to provide the device with an attaching portion for the cap which will permit the cap to be formed :of one piece and positioned .on the device with its rim practically against the container wall. I

Yet another object of the invention is to provide particularly effective means for .preventing. any leakage of the container contents between 'the various parts of the device.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in. the following description of the preferred form of the invention. which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention" as set forth in the claims.

- Referring to said drawing:

Figure 1 is aplan view of the device with th enclosure cap in. position thereon, portions being broken away and shown in section in order to show the hidden parts.

Figure 2 is a longitudinal sectional view of the assembly shown in Figure 1, the plane of the section being indicated by the line 22.

Figure 3 is a view, half in section and half in side elevation, showing the parts of thedevice as they appear before being assembled.

Figure 4 is a fragmentary sectional view similar to Figure 2, but showing a somewhat modified design of the device and enclosing cap.

The device of my invention as illustrated in Figures 1 to 3 inclusive is designed for use on a metal container wall 2 provided with an outward oflset or embossment 3 formed with a cylindrical portion 4 and an outer portion 5. In offset portion 5 is provided an opening 1 in' which is positioned a bushing ring 8 here shown with an internally threaded opening 9 arranged for the reception of a threaded closure l2. Seated within the recess l3 formed at the inner side of the container wall by the offset 13 is a flange l4 preferably formed integrally with the bushing ring and arranged to underlie the offset portion 5 and form a substantial backing or support therefor.

The central or body portion of the bushing ring projects from the container wall at the outer side thereof, and embracing such projecting portion of the ring is a sleeve l formed at the inner periphery of an annular reenforcing member l8. The latter is provided with a laterally extending po'rtioul! which as will be clear from Figure 2, bears upon the outer surface of the offset portion 5 of the container wall so as to provide a backing therefore substantially over its entire area. The member i8 is desirably formed of sheet metal of a thickness at least as great as that. of 30 the container wall and therefore provides an effective reenforcement for both the bust ing body and container wall.

For holding theparts against axial displacement on the container, the outer end 2| of the ring body is flanged over the corresponding end of the reenforcing sleeve ll, thereby clamping the .member and wall against the flange l4. To prevent rotative displacement of the parts the flange I4 is provided on the side against the wall, with a plurality of projections 22 which seat in recesses 23 in wall portion 5, formed by providing offsets 24 therein. The protruding sides of the offsets in turn seat in recesses 20 formed in corresponding onsets in the laterally extending portion I9 of the member i8. It will thus be seen that when the parts are in operative assembled relation on the container wall, neither the bushing ring nor the reenforcing member may be displaced rotatively relative to each other or to the wall. It is important to note that by reason of the fact that the projections 22 are on the flange It, the oifsets inthe wall and reenforcing member may be formed by merely. forcing the flange against the wall while a suitably recessed 55 enforcing member. After the end 2| has been flanged over as aforesaid, which operation if deincluding the closure plug and the wall offset.

sired may be effected at the time the projections form the offsets, the parts of the device will be most securely locked in position, it being understood that by reason of the firm grip which the flanged end has about the ring sleeve, the locking engagement between the reenforcement member and wall will also materially aid in preventing rotation of the ring on the wall.

, By reference particularly to Figure 2, it will be seen that the projections 22 are disposed preferably exclusively near the outer periphery of the flange so as to leave clear the surface near the inner periphery. On such surface there is seated a resilient gasket 25 which is arranged to be forcibly compressed when the parts of the device are clamped together as aforesaid. Preferably the body of the bushing ring lies somewhat spaced from the edge of the wall at the opening I so that when the gasket is compressed is will fill such space and forcibly bear simultaneously against the ring, wall, and reenforcing member. In this way a triple seal is provided, that is between fiange and wall, between the wall and the portion l9 of the reenforcing member, and between the sleeve of the member and the body of the ring.

An important part of the present invention lies in the feature of adapting the device for enclosure by a cap or hood so as to guard or shield the device against tampering and prevent unauthorized, or at least undetectable, access to the closure plug. As will be most clear from Figures 2 and 3, the member I8 is designed to extend laterally considerably beyond the portion of the ofl'set 3 engaged thereby, and is formed at its outer periphery with a head 26 which extends toward the wall so as to lie in the space surrounding said oifset. The bead 26 while being desirably disposed in extreme proximity to the container wall proper, is preferably sufhcientlyx spaced therefrom to permit of the insertion therebetween of the rim 2'! of a cap or hood 28 arranged to enclose the device. The cap 28 is here shown of one piece and designed to provide a complete enclosure for all parts of the fitting In the forms of the invention illustrated, the cap is arranged to be interlocked with the member by crimping the rim 21 about the bead 26, and as shown in Figures 2 and 3, the rim is formed with tongues 29 designed to extend over and around the bead so as to substantially close the space between the' bead and the adjacent surface of the wall. A gasket 3| may be positioned within the rim of the cap so as to seal the space within the cap and facilitate the resilient gripping of the bead by the rim. It is to be noted that since the laterally extending portion of the reenforcing member projects substantially perpendicular to the fitting axis, for its entire width, no difllculty will be encountered in having to force around the bead the rim portion of a cap even when the latter is formed of relatively heavy gauge sheet metal.

In the 'form of the invention illustrated in Figure 4, the rim 21' of the cap 28' is formed smooth, that is without the tongues 29. With this design the. use of a comparatively light gauge sheet material for the cap is particularly appropriate, since the tampering with or removal and replacement of the cap, can be readily detected. In this case, as in the previously de- 2,031,351 'die is held against the exposed side of the rescribed embodiment the outer periphery or bead 26' of the member I8 is brought in close proximity to the wall so that the cap will provide a more complete enclosure for the device and at the same time make more diflicult its unauthorized removal.
